Rates of theft have fallen up to 65 percent in stores that have the technology installed

According to a report released by national police force Rigspolitiet, the new DNA spray system, used as an anti-theft measure by banks, supermarkets and other institutions, is proving effective at deterring potential robbers from carrying out crimes.

Rigspolitiet conducted an experiment testing the effectiveness
of the technology in 42 grocery stores around Copenhagen and found that in some cases the rates of theft fell by as much as 65 percent.

Better safe than sorry
The report, which was released in conjunction with the Confederation of Danish Enterprise and the Danish Association for Safety and Security, found that institutions employing the measure have reported a significant drop in the number of thefts.

“DNA spray works to deters thieves from committing the robbery, so it has great crime prevention value,” said lead researcher, Rune Holst Scherg.

The technology, which works by surrounding the robber in a cloud of invisible spray containing a unique DNA signature, lingers on the body of the suspect anywhere between four to six weeks and can be traced on clothes for up to a few months.

Since each spray has a unique DNA signature, a database can be used to trace it back to the store in which it was set off.

A survey carried out by Megafon for TV2 has found that 71 percent of parents have handed over children to daycare in spite of them being sick.

Moreover, 21 percent of those surveyed admitted to medicating their kids with paracetamol, such as Panodil, before sending them to school.

The FOLA parents’ organisation is shocked by the findings.

“I think it is absolutely crazy. It simply cannot be that a child goes to school sick and plays with lots of other children. Then we are faced with the fact that they will infect the whole institution,” said FOLA chair Signe Nielsen.

Pill pushers
At the Børnehuset daycare institution in Silkeborg a meeting was called where parents were implored not to bring their sick children to school.

At Børnehuset there are fears that parents prefer to pack their kids off with a pill without informing teachers.

“We occasionally have children who that they have had a pill for breakfast,” said headteacher Susanne Bødker. “You might think that it is a Panodil more than a vitamin pill, if it is a child who has just been sick, for example.”

Parents sick and tired
Parents, when confronted, often cite pressure at work as a reason for not being able to stay at home with their children.

Many declare that they simply cannot take another day off, as they are afraid of being fired.

Allan Randrup Thomsen, a professor of virology at KU, has heavily criticised the parents’ actions, describing the current situation as a “vicious circle”.

“It promotes the spread of viruses, and it adds momentum to a cycle where parents are pressured by high levels of sick-leave. If they then choose to send the children to daycare while they are still recovering, they keep the epidemic going in daycares, and this in turn puts a greater burden on the parents.”
